How to Upgrade Your Ender 3 Power Supply to a MeanWell PSU
Aside from upgrading your Ender 3 board, upgrading your stock PSU to a Mean Well PSU is one of the best upgrades to make your 3D printer quieter.
In this guide, I'll show you how to upgrade your Ender 3 to the MeanWell LRS-3500-25 PSU. This is the same power supply used on the Ender 3 Pro.
Why upgrade?
There are several reasons to upgrade your Ender 3's PSU to a Mean Well:
- Noise: The PSU fan only runs when needed (usually <20% of the time), meaning a much quieter printer.
- Safety: MeanWell power supplies are more reliable and safer than the cheap stock unit. They use higher-quality components that provide consistent, clean power with fewer spikes and sags.
- Reduce bed-leveling issues: By providing consistent power the MeanWell reduces issues with EZABL and other bed-leveling kits related to power ripples and grounding.
- Compact form factor: The MeanWell PSU is noticeably thinner and more compact than the stock unit; this is especially handy if you're using an enclosure and want to keep your setup as compact as possible.
